David Schultz f2c7668eb1 Make ps_nargvstr and ps_nenvstr unsigned. This fixes an input
validation error in procfs/linprocfs that can be exploited by local
users to cause a kernel panic.  All versions of FreeBSD with the patch
referenced in SA-04:17.procfs have this bug, but versions without that
patch have a more serious bug instead.  This problem only affects
systems on which procfs or linprocfs is mounted.
